A disabled man on a mobility scooter and a Serve Robotics cart collided after the man says the cart repeatedly cut him off. The incident occurred in West Hollywood where there are plenty of Serve Robotics carts that are primarily autonomous, loaded with food and out for delivery. The company says the robots are designed to "navigate respectfully around all people" and in this case "the robot… came to a full stop after attempting to cede the right of way."
